Installed a AVIC-N3 into a 2004 Jeep Grand Cherokee. I want to connect the VSS wire. I found a Wire Diagram that stated their should be a white/orange wire in the instrument cluster at pin 4, but no such wire exists. I would like to find a location I can tap off of inside the vehicle so I do not have to go through the Firewall. I do have Cruise Control built into my steering wheel, not sure I can use the wire from there. Thanks for any Information in advanced.

To my knowledge the only way you can get vss inside that truck is using a canbus interface. Without that, I'd say you'll be going to a wheel speed sensor for vss.

Thanks for the info. Someone on the12volt.com forum directed me to the PCM, Dark Green / Yellow, Pin 27. Installed yesterday and looks to be working great. Going through the firewall in this car wasn't as bad as my other cars were.
